RAILWAY-TRACK BALLAST GRADING AND sunmcme macnnm,

Application filed December 2, 1922. Serial No. 604,566.

Washington, have invented certain new and useful Improvements inRailway-Track Ballast Grading and Surfacing Machines, of which thefollowing is a specification.

This invention relates to railway-ballast surfacing machines anditsobject is to produce a machine of this character which will be moreeflicient than others hitherto in use.

More specific objects and advantages of the invention will appear in thefollowing description.

The invention consists in the novel construction, adaptation andcombination of parts hereinafter described and claimed.

In the accompan ing drawings,-

Figure 1 is a p an view of devices embodying my improvements shownapplied to a portion of a railway car. Figs. 2, 3 and 4 are Verticaldetail sectional views through 2-2, 3-3 and 44 of Fig. 1. Fig. 5 is ahorizontal sectional view through 55 of Fig. 4. Figs. 6 and 7 arevertical sectional views through 66 and 7 -7 of Fig. 1. Fig. 8 is avertical section through 8- -8 of Fig. 6. Fig. 9isahorizontal sectionthrough 9-9 of Fig. 8. Fig. 10 is a planview illustrating thearrangement of the inter-tie grading devices. Fig. 11 is a frontelevational view of the ballast surfacing devices and the casing supporttherefor shown in vertical section. Fig. 12 is a sectional view through12-12 of Fig. 11.

In the drawings, the reference numeral 10 designates the frame of a carbody supported by wheels 11, 11 tracking upon rails such as 12 which arelaid upon ties 13.

The various members or organizations of parts hereinafter described areillustrated as applied to but one side of the car although it is to beunderstood that duplicate or similar organizations of parts would beemployed at the opposite side of the car.

1 In the present invention said car body frame is formed or providedwith vertical guide ways 14 to receive rib elements 15 provided upon ahorizontally disposed beam member 16 of a frame which is adjustable toselected elevations by means of regulating screw 17. Adjacent to itsforward end the beam member 16 is provided with a laterally protrudinghollow portion 18 into which extends the outer end of a bar 19 disposedtransversely of the car.

Said bar is operatively connected intermediate its length to the crankpin 20 (Figs. 4 and 10) of a longitudinally disposed power driven shaft21 which is rotated in the y vating movement during the inward or returnstroke.

Rigid with, bar ;19 and within the .frame'portion -IS. is a head 23having a pair" of vertically. spaced bracket elements 24 and 24 providedwith; apertures which serve'fas guideways for vertically movableteeth'25,

see Figs. 3 and 4, which are yieldingly held in thei lowermostjpositionswith respect-to said head by means of springs 26.

The relative vertical movements of said.

teeth are individually controlled as by the provision of slots 27 in theteeth to receive I pins 28 which are rigidly secured to the head. Thefront lower corners of the respective teeth are chamfered, as shown inFig. 3, to provide beveled surfaces which upon encountering a track tie,as 13 for example, in the forward travel of the carindicated bydirection arrow Bto effect the raising of the successive teeth to passover the tie. In operation the teeth 25 in their outward strokes withsaid bar act to push accumulations of earthymaterial outwardly frombetween adjacent ties to a substantially level plane slightly below theplane of the upper surfaces of the ties.

ocated in advance of the frame part 18 and secured thereto above theties 13 is a plow blade 29 which is arranged as shown in Figs. 1 and 2,that is to say in a substantially vertical plane disposed at an angle tothe car frame and with its inner edge foremost.

Adjacent to its lower edge the plow blade 29 is provided upon its frontside with a plurallty of transversely inclined projections 30, as shownin Fig. 2, whose function is to direct material in the path of the plowblade to in front of the hereinafter described-ballast surfacing andgrading mechanism. V

' In the present invention this grader comprises two endless belts 31and 31 disposed laterally of the car and passing about driving wheels 32and 32 and guide pulleys such as 33 and 34.

36 represents a shaft to which the wheel 32 is secured andupon which thewheel 32 is mounted to rotate independently thereof.

The shaft 36 is driven through the medium of shafts 37 and 38 and bevelgears 39 from the car wheel axle 40 when the car is in motion. 1

The wheel 32 is rotated with the shaft 38 to drive the belt 31 in thedirection indicated by arrow :1: in Fig. 4, and the other belt 31 isdriven in the opposite direction throu h the instrumentality of a bevelgear 41 (Fig. 5) mounted on a stub shaft 42 and meshing with teeth 43provided on the respective Wheels. Each of said belts is provided withdigging and scraper attachments such as 44, Fig. 4, whereby the materialupon the ballast at 45 is moved toward the track by the attachments ofthe belt 31 and away from the track by the attachments of the other belt31 To regulate the belts to accommodate difierent slopes of the ballast,the guide pulleys 33 are mounted upon a shaft 46 which is journaled in ablock 47 (Fig. 6) movable vertically in a guide 48 mounted for verticalmovement on a frame 49, such motion of the block 47 is attained by meansof a screw -50 connected to said block and engaging in a nut 51 which isrigid with the guide 48. As illustrated in Fig. 6, the screw 50 extendsinto and has a spline connection with a hollow shaft 52 which is rotatedtoefiect the raising or lowering of the shaft 46 and the pulleys thereonby means of bevel gears 53 from a manually operable crank shaft 54.

The guide 48 above referred to is itself vertically adjustable in guidebars 55 of the frame 49 by the provision on the guide of a rack element56 being influenced by a pinion 57 upon a shaft,58 which also carries apinion 59 which is rotated by a rack bar 60 connected to a lever 61fulcrumed at 62 to the frame 49.

The lever 61 is connected by a link 63 with a controlling lever 64.

The shaft 65 for the belt pulleys 34, serves as the 'pivotal'connectionbetween two links 66 and 67, of which the link 66 is connected at 68 tothe guide 48 and the link '67 is connected at 69 to a block 70 which issecured by means of a bolt 71 in vertically adjustablepositions to theframe 49.

belts to correspond with a desired ballast slope. V

The frame 49 is made hollow to receive therein surface dressing blades 7272 having their lower ends serrated as at 73 and a gutter forming blade74 whose lower end, preferably, is not serrated. p

The blade 72 closest to the car frame, see Fig. 11, is pivotallyconnected by a pin 75 to the frame 49 and the other of said blades arepivotally connected with each other in series by pins 76.

The blades 72 172 are each provided with a stud 77 extending throughguide slots 78 provided therefor in a plate 79 which .is pivotallyconnected adjacent one of its ends to the pin 75.

The blade 74 (Fig. 7) is connected to the frame 49 by the )rovision ofguide pins 80 thereof exten ing through slots 81 provided in the blade,said slots being inclined to accommodate the arcuate movements of theseries of serrated blades 7272 and maintain the blade 74 insubstantially vertical position in the various adjustments of the blades72-72 The plate 79 is operatively connected by a link 82 to the lever 61so that when the latter is employed to regulate the scraper belts theplate is simultaneously swung up or down about its axis 75 to cause saidblades to be brought into positions to dress the ballast surface to apredetermined grade or slope.

Associated with said blades and.respectively connected therewith arerearwardly extending brackets 83 in which are jour naled the axles ofrollers 84, shown in Figs. 7, 8 and 9.

The frame 49 which sup-ports the grading and dressing devices aboveexplained is hingedly connected to the main frame 16 for horizontalswinging motions by means of a pin 85 extending through apertured lugs16 and 49 provided on the respective frames. The angular position ofthe-frame 49 with respect to the car is regulated by means of a screw 86rotatable in a boss 87 on the frame 16 and engaging in a nut 88 attachedto one of a pair of toggle links 89, 90 connected to the frames 16 and49 by pivot pins 91.

The car to which my devices are applied is desirably propelled by amotor, not shown, mounted upon the car, such motor being utilized todrive in opposite rotary directions the shafts 21 and 21 through themedium of known or suitable transmission mechanism.

In operation, the plow 29' is regulated to have the lower ends of theplow teeth or projections as close to theplane of the upper surfaces ofthe track ties 13,13 as permitted so that in the forward travel of thecar the tops of the ties are practically cleared of earthy material.

Following said plow is the laterally reciprocating bar devices carryingvertically movable teeth 25 which act to push the material from betweenthe successive track ties to a level somewhat below. the plane of theupper surfaces of the ties. The material displaced by said plow and thereciprocatory teeth 25 beyond the adjacent ends of the ties isencountered by the scraper attachments 44 of the belts 31 and 31, thelower leadsof which, that isthe parts of the belts between the wheels32, 32 and the respective pulleys 33travel in opposite directionswhereby the surface material on the slope is moved alternately towardand from the track for the purpose of spreading or distributing suchsurface material to ensure a substantially even surface.

Following such distributing devices are the surface dressing devicescomprising the blades 72-72 and the gutter forming blade 74 of which theformer serve to remove gravel, lumps of clay, or the like, from .thesurface and to form the contour thereof to an arcuate shape and directsurplus material into the path of the blade 74 which, in turn, affords aledge or finish at the outer edge of the sloping portion of the ballast.Finally the rollers 84 travel over the surface of the slope to renderthe same compact and firm.

By means of the controllin lever 64, the surfacing blades 72, 72 and 4,the rollers 84 and the conveyor or grading devices 31 and 31 areregulated in unison to accommodate from the horizontal.

The operation and advantages of the invention will be understood fromthe foregoing description.
